Internet Protocol Support

The Internet is a collection of networks and gateways that use Transport Control Protocol/Internet Protocol (TCP/IP) to handle data transfer and message conversion from the sending network to the receiving network. An Internet protocol is a set of standards designed to enable different types of computers to communicate with one another and to exchange information through the Internet.

In addition to providing Simple Mail Transfer Protocol (SMTP) support, Microsoft Exchange Server supports the following:

• Internet News Service/Network News Transfer Protocol (NNTP)
• Post Office Protocol version 3 (POP3)
• Internet Message Access Protocol, Version 4rev1 (IMAP4rev1)
• Lightweight Directory Access Protocol (LDAP)
• Hypertext Transfer Protocol (HTTP)

You can set properties for Internet protocols at the site level or at the server level by using the Microsoft Exchange Server Administrator program. For more information on configuring properties for NNTP, POP3, IMAP4, LDAP, and HTTP, see Microsoft Exchange Server Operations.
